Building 51450 will house the INSCOM Det 52 Detachment (DET 52), INSCOM G2X Program Management Offices (G2X PMOs), an Army Operations Group (AOG) element, and Army Field Support Center (AFSC) matrixed support. Building 51451 will house elements of the 308th and 310th Military Intelligence Battalions (MI BNs)of the 902nd Military Intelligence Brigade (MI BDE), the INSCOM G2 Security Operations Center (ISOC) Response Branch West Fort Huachuca Office, and AFSC matrixed support. The scope of work is based on the conclusions of the January 2019 Jacobs Space Planning Report and the Wiley|Wilson Field Investigation and Charrette Report, dated January 3, 2020.

EXISTING CONDITIONS

Buildings 51450 and 51451 were both built in 1969 as compact item repair shops. The buildings have been vacant for at least the past five years. The buildings are similar in size, with building 51450 being 8,280 GSF, and 51451 being 6,960 GSF. Both buildings are in need of major renovation to adequately serve the proposed tenants. Building 51450 shows signs of significant water intrusion and damage due to the failing roof system. A hazardous materials survey performed during the field investigation phase found asbestos containing materials and lead based paints in both buildings.

DEMOLITION

Demolition involves gutting the interiors of both buildings and leaving only bearings walls, floor slabs, and roof structures. Additionally, adjacent buildings 51449, 51452, 51453, and 51454 are to be removed.

CIVIL/SITE

The site encompasses approximately 3.3 acres. Parking will be provided for a total of 96 vehicles; this includes 86 POV, 4 ADA and 6 GOV (screened from view). New site walkways and egress paths will also be provided.

USACE/RSFO UNCLASSIFIED // FOR OFFICIAL USE ONLY Page 5

DEMOLITION

The demolition of this site includes the removal of buildings 51449, 51452, 51543 and 51454, as well as all associated utilities and retaining walls. The loading ramp to the south of 51450, all electrical boxes along the front porches, AC units and any miscellaneous structures west of 51450 and 51451 will be removed along with any associated concrete pads. The removal of existing asphalt will be limited to the areas within the 80’ standoff and areas with new grading.

PROPOSED SITE PLAN

1) Grading The site will be graded to drain stormwater runoff away from the buildings, walks, and parking areas primarily through overland (sheet) flow. The proposed re-grading of the site will generally maintain existing overall drainage patterns, maximize the cut/fill balance onsite, and adhere to ADA, local, state and federal regulations. Low impact storm water management practices will be used to pre-development hydrology and prevent any net increase in storm water runoff will be maintain.

The site has been conceptually developed to minimize the earthwork requirements necessary for construction and balance within reason the amount of materials brought on and off site.

2) Utilities Existing water and sewer lines will be removed from the west side of building 51450 and new 2” domestic water and a 4” sanitary sewer lines will be connected to the existing main lines. Building 51451 will use the existing domestic water line connection, while the existing sanitary line will be removed and a new 4” sanitary connection will be added to the existing main line. All current gas line locations will remain in place. A new gas line will be added connected to the new standby generator and building 51451. The large transformer between buildings 51450 and 51451 will remain in place. All utilities will be have the minimum land coverage and spacing per UFC requirements.

3) Roadways and Pavements Concrete pavement will be used for the sidewalks, dumpsters and ADA parking and ramps.

Equipment pads will be added for the two new HVAC systems behind buildings 51450 & 51451. An equipment pad will be added for the new standby generator behind building 51451. Sidewalks will be 5 feet in width. The site will include landscape elements(landscape rocks) around buildings 51450 and 51451. There will be 96 parking spaces available(86 POV, 4 ADA, and 6 GOV screened). The screened parking will be located in the northwest corner of the site and will have controlled gate access. All pavements will be designed using the most current UFC standards.

The access road will be approximately a 26-ft wide, clear, paved entrance. The entrance/exit design will be such that it ties into the existing roadway in a safe, efficient, and functional manner. Adequate safe sight distances will be provided for the

USACE/RSFO UNCLASSIFIED // FOR OFFICIAL USE ONLY Page 6 entrance/exit point. All entrances and exits will be designed to provide clear, unobstructed ingress and egress from the parking areas. Vehicle entrances and exits will be designed to ensure that safe sight distances are provided, as required.

A fire lane will be implemented according to the Fort Huachuca specific fire requirements.

The 20’ wide geotextile fire lane will be west of buildings 51450 and 51451 and loop around the south end of 51450 to connect to the proposed access road. Existing fire hydrants will remain in place.

6) Borrow Material To the extent possible, materials anticipated from the earthwork activities on site will be processed and reused on site where acceptable. Where additional materials are required to be hauled from off site sources to meet project specifications, the materials will be tested for contamination prior to being hauled and stockpiled on site.

OVERVIEW

The U.S. Army Corps of Engineers (USACE) and INSCOM are planning to renovate two existing buildings, 51450 and 51451, located at Ft. Huachuca. Renovation will bring the buildings up to current building, fire, and accessibility codes as well as address problems like failing roof systems, etc. The buildings will consolidate individual INSCOM activities, which are currently scattered around the base, to a single location. Currently, the spaces occupied by each group do not meet their space and security needs and the new buildings will address these deficiencies as well. Building 51450 will house the INSCOM Det 52 Detachment, INSCOM G2X Program Management Offices (G2X PMOs), an Army Operations Group (AOG) element, and Army Field Support Center (AFSC) matrixed support. Building 51451 will house elements of the 308th and 310th Military Intelligence Battalions (MI BNs) of the 902nd Military Intelligence Brigade (MI BDE), the INSCOM G2 Security Operations Center (ISOC) Response Branch West Fort Huachuca Office, and AFSC matrixed support.

USACE/RSFO UNCLASSIFIED // FOR OFFICIAL USE ONLY Page 12

EXISTING CONDITIONS

Buildings 51450 and 51451 were built in 1969 as compact item repair shops. The buildings have been reconfigured several times for various motor pool and warehouse-type functions. Both buildings have sat vacant for the last five years. The buildings are roughly the same size with building 51450 being 8,280 SF and 51451 being 6,960 SF. Construction is similar with non-reinforced masonry exterior walls and a steel roof structure, though 1/3 of the roof structure of 51451 changes to a concrete system. Front and rear exterior walls are load bearing allowing for the interiors to be free of load bearing walls with the exception of the concrete roof section of 51451 which requires an interior CMU bearing wall and a concrete column. The roof systems on both buildings need to be replaced as they have both been patched several times. Building 51450 shows signs of significant water intrusion and damage due to the failing roof system. Existing toilet rooms in both buildings do not meet current code. Building doors, walls, interiors, and other elements are well worn and in need of replacement. A hazmat survey performed during the field investigation of the buildings found substantial amounts of asbestos. Refer to the hazmat report provided in the appendix of this document for more information.

DEMOLITION

Demolition for both buildings will be largely similar. The interiors will be completely gutted leaving only the exterior walls, floor slab, and steel roof structure. Additionally, the interior load bearing wall and concrete column in 51451 will also remain. All exterior man doors, barn doors, roll up doors, and windows will be removed. Rough openings for new doors will be cut into the exterior walls. The roof systems on both buildings will be removed and the deck prepped for the installation of a new membrane roof. Both buildings have concrete loading dock platforms running the length of the front wall. These loading docks are outfitted with bumpers that will be removed.

LIFE SAFETY AND FACILITY CIRCULATION

The buildings are non-combustible structures. Both will be protected by a wet pipe sprinkler system and fire alarm system.

ANTI-TERRORISM / FORCE PROTECTION SYSTEMS

In accordance with DoD Uniform Facilities Criteria - UFC 4-010-01, the basis of design for the new buildings is designated as normal. The buildings are inside a controlled perimeter.

See Section 1.12 ATFP Narrative for additional information.

SUSTAINABILITY CONSTRUCTION GUIDELINES

The renovation of the buildings will follow UFC 1-200-02 High Performance and Sustainable Building requirements. Architecturally this will include the specification and use of environmentally certified products, including recycled and recyclable products, flooring systems, and low-emitting materials such as low-VOC adhesives and sealants, paints, and coatings. Locally manufactured building products will be specified when possible to reduce the environmental impact of the long distance hauling of building materials.
